Up for sale is my Cornerstone Colosseum in excellent condition. This was Cornerstone's first "Community Pedal" — designed with direct input from their fanbase — and it's a genuinely versatile dual-overdrive that punches way above typical boutique clones.

Why it's special:

• Two independent overdrive channels in one box: a reworked Blues Breaker-style circuit (clipping diodes removed, tone controls refined to fix the classic BB's low volume and dark tone) and a Klon-style circuit, both studied against original vintage units including an authentic Klon Centaur
• Each channel has its own Gain, Volume, and Tone controls
• Central toggle switch lets you reorder the channels (BB into Klon, or vice versa) for different stacking flavors
• "Clean" mini-knob blends in your dry signal in parallel with the overdrive, preserving pick dynamics and headroom — the same trick used on Cornerstone's acclaimed Gladio SC
• 100% in-house machined enclosure with an elegant antique white finish, boutique-grade PCBs and components throughout

Condition: Excellent. Minimal signs of use — a couple of very light, barely noticeable marks from normal handling, but no dents, scratches on the graphics, or functional issues. Fully tested, all knobs and switches work smoothly. Velcro already applied to the back, so it's ready to drop straight onto a pedalboard.

A fantastic 2-in-1 overdrive for anyone chasing classic Blues Breaker or Klon tones with more flexibility than the originals. Fast, secure shipping.
